Wattkins Universal Chassis

We sold out of the original chassis run, and based on feedback we've received, we've made the next batch better with a few minor updates. The tube sockets and PCB mounting holes have been moved closer to the front panel providing more space for the output transformer, there is an extra pilot hole for the IEC ground, and 10/32" cage nuts are included.

This is a very sturdy 16" x 8" x 2.5" universal chassis that was designed to be compatible with our Universal PCB, as well as the 5E3 Tweed Deluxe PCB.

The chassis is the standard 16" x 8" size, except we've made some improvements. It's a 1/2" taller than standard to make it easier to work on and accommodate more parts.

It's also comes with pre-drilled holes for switches, lamps, pots, and jacks, as well as all cut-outs for the Tweed 5E3 PCB. It will work with most Valve Junior-compatible PCBs and turret boards (such as the Baby Will PCB) with very minor modification.
